in 11 vii-om it may concern.

Be it known that I. ruman ammy her. a citizen of the United States.residing at lavetteville. in the county of lVashing- 1 ton and State ofArkansas, have invented certain new and useful improvements inRevolvers; and i do hereby declare the tollowing to he a full. clear.and exactdescription er the invention. such will enable others skilledin the art to which it appertains to make and use the same.

One object of the invention is to insure accuracv of rapid shooting.

Another object is to reduce the strain upon the arm and hand in holdingand tiring the revolver.

It is also my aim to form the handle so that it will not only be inposition to balance he revolver in such a manner as to insure accurac inshooting but so that it will conform naturally to the hand and willconseturentlv be restful rather than tiresome in the grasp.

.znother object is to provide means for carrying an extra round ofcartrid es in the revolver where thev will be accessible for ."liate usein an en'iergency.

iurther object is to reduce the length of the revoivcr over all;compared with the length of the harrcl. whereby the barrel may he .nadelonger than in other revolvers without increasing the entire length ofthe. weapon.

.inothe ohject oi my invention to provide improved and thoroughlyreliable locking means for fastening the breaking portionsv of therevolver together. a secondary loch heing cniplovcd to prevent the.acci-L dental opening of the revolver when in use or when handled by aninexperienced person.

further object is to automatically lock the trigger when the revolver isopen therein preventing said tri from being pulled the revolver is beingloaded. This znridentallv cocking the revolver. while loading. thuspreventing accidental dis-;

charge after the weapon has been loaded and closed.

It is also my aim to prevent sparks from flu x 1 7 l MI "I r n in w I'iw f v v 1 (v1.1a. tron. .arning t..c ingei. liltll I extended alongthe frame and engaged with the trigger for firing the revolver.

notn.er cl eet to improve the constructron and operation of the triggermechanism wherehvit will be easier to operate and will 3 in addition toraising and releasing the hammer, the trigger is designed to unlock thecylinder. to lock the hammer against accidental discharge, and tooperate the mechanism tor revolving the cylinder.

.irnother object of my invention is to provide improved operativeconnection between the trigger and hammer whereby the hammer and itsoperating arm cannot become separated or loosened while in the revolverbut may be instantly detached or connected when removed from the gun.This connecting device constructed with a view ing back the hammer. assaid trigger is pressed back. for automatically tripping said hammer andfor returning said hammer when released, as in a hammerless revolver.The hammer is also adapted to be with its retracted position. Thetrigger is designed to automatically release the hammer when used inthis manner.

further object is to provide an improved accidental discharge lockoperated by the trigger and serving to prevent the hammer from movingforward a sufiic-ient distance to bring its firing pin into contact withthe cap on the cartridge without pressing said trigger.

i till another object is to provide an improved ejector which is simplein construction. reliable and automatic in its operation. The cylinderis retained in position while y the ejector moves back and forth as thet revolver is opened and closed.

Other objects will become apparent from the following description.

1 T he inventionconsists in the features of i construction andcombinations of parts hereinai'ter described, illustrated in theaccompanving drawings, and specified in the appended claims. a in theaccompanying drawings: Figure l a side elevation of my revolver completeK when used for automatic firing. Fig. 2 is an enlarged broken side viewof the revolver with the adjacent side plate removed.

Fig. 9 is a detailed view of the hammer. Fig.10 a detailed view of the two part connection between the trigger.ham1ner-actuating slide top plan view oi the lock shown in Fig. 13.

Fig. 15 is a sectional view through the fastening device for the upperforward end of the detachable cap. the removal of which converts therevolver from the hanunerlcss to the hannner type. and Fig. 1G is atransverse vertical sectional view through the lock which secures theclosure of the eartridge storing chamber in the handle.

Referring more particularly to the drawings, l designates the lower partof the. revolver which carries the firing mechanism. and 2 indicates theupper part including the barrel and cylinder 14. The two parts arehinged together by a pivot pin 5. passed through overlapping pairs ofpivot lugs 1 and 2 on the parts 1 and and secured by a small screw seeFigs. 1 and 5.

0n the front end of the cylinder there is formed a projecting collar 6normally engaged by a spring-pressed hook 7 whereby said cylinder isretained in proper longitudinal position with respect to the other partsof the revolver but is free to be rotated for successively lnfinging thecartridges into position for firing. This hook T provided with a smallhandle or projection for releasing it from the collar (3 when it isdesired to remove the cylinder for cleaning the same.

The ejector rod 9 passes through the cylinder in the customary way. Theforward end of said rod extends into a chamber 10 in the part 2 of therevolver. Mounted in said chamber. upon the pivot pin 5 as an axis. asegmental gear 11 meshing with a As 3. said segmental gear: has adisk-shaped offset portion 13 arranged This offset porrack 12 on the endof the ejector rod. illustrated in Fig.

between the pivot lugs 2 tion or disk has a channel or groove 1-l formedin its surface W onally thereof. the through its center. said channel orgroove are partially closed by flanges 15 which terminate short of thelower lateral edge of said channel leaving openings 16 at each endthereof. In said channel is fitted a lQCiPlOCtltlng pivot pin projectingpivot pin Fig. 12 is an enlarged- The opposite ends of to the elongatedslot 18, leaving a resilient I finger 21 which serves to hold the plateinv i i l l l I l l l j l l l l j l g i l l and extending diagplate 1?having an enlarged slot 18 embracing the One end of the plate is made ieither of its positions in the channel without en'iploying a separatespring. Projections and 23 are formed on the opposite ends of the plate17 and are capable of being on tended through the openings 16 at theends of the channel. The length of the plate, exclusive of itsprojections, is somewhatless than the distance between the flanges 15 atthe ends of the channel so that said plate is capable or having areciprocating movement. The length of the projections and is such as tobring one of theln flush with the periphery of the offset por tion 13 atone side thereof when the plate at the end of its stroke in the oppositedircction, that is to say. when the opposite end of said plate is inengagement with the cor V responding flange 15. In this position theprojection on the last mentioned end of the plate will extend throughthe corresponding opening 16 beyond the periphery of the disk 13.

The projections 22 and are preferably formed as extensions along thelower lateral edge of the plate 17. The lower sides of said projectionsare straight. as at 2st, but their upper sides are rounded or beveledrasat 27. see Fig. 6. \Vhen. the revolver is closed. the lower projection22 engages a shoulder 26 on the lower part 1 and the projection isarranged in line with the meet ing edges of said lower part and theupper part 2, but said projection 21) is held within the periphery ofthe disk 13 by the abutting edges of said lower and upper parts. Whenthe revolver is opened, the projection 22, engaging the shoulder 26,holds the segmental gear 11 rigid upon the lower part as the upper partis swung away from it. The result is that the eject-or rod is movedlongitudinally, by reason of the segmental gear acting upon the rack 12,to remove the cartridges from the cylinder. hen the parts 1 and 2 areopened to the fullest extent. the lower face of the upper part, at 27.engages the inclined side of the projection and in riding up itforcesthe plate 17 upwardlv until said projection is re tracted within theperiphery of the disk 13. and the projection is extended. beyond thesame along the upper surface of the part 1 at 28. see Fig. el. Theprojection 23, engaging the iower part, at segmental gear 11 rigid uponsaid lower part while the upper part is closed upon it. hen the twoparts come together in closed position. the lower surface of the upperpart. at 29, engages the beveled side of the projection 23 and forcessaid projection back into the periphery ,of the d sk 13. ex tending theprojection 2? into its initial po- 28. holds the sition. The operationof the ejector, is therefore, entirely automatic. The formation of theplate 17 with the resilient finger 21 retains it in either of its twopositions until it is moved to the other position in the operation ofopening and closing the revolver as just explained.

The handle is arranged below and intermediate of the ends of therevolver, preferably beneath the cylinder. At the top of the front edgeof the handle there is a groove 31, separated by a forwardly projectingpoint 32 from the lower part of the handle, to receive the second fingerof the hand when clasped around said handle. The confining of thisfinger within the groove aids in supporting the revolver in the properlevel position in the hand. The arrangement of the handle below theheaviest part of the gun makes it balance more naturally, removing thestrain on the hand and causing the barrel to normally lie in a levelposition when the revolver is in operat-ion. thereby making itcomparatively easy to aim the weapon and saving considerable time infiring rapidly, as well as insuring accuracy.

The interior of the handle is hollowed out to form a chamber 33 for thestorage of an extra round of cartridges. One side. 34:, of the handle ishinged at 35 and constitutes a closure for the chamber 33. Said closureis provided with a hook shaped lug 36 in its inner face and registeringwith a recess 37 in the edge of the handle. Said recess extends down tothe base of the handle and contains a springpressed catch 38 having ahook 39 at its upper end adapted to automatically interlock with the lug36 on the closure 3%. The lower end of the catch 38 formed into theshape of a button 40 which is countersunk in the handle, as at 41, spacebeing left to permit the necessary vertical movement of said button forreleasing the latch from the lug on the closure when it is desired toopen the latter.

The lower part 1 of the revolver is provided with a finger opening orslot 41 located just behind the pivot pin 5 and ejector disk 13. Saidfinger opening extends parallel to the barrel and into it extends thefinger piece 12 on the forward end of the trigger slide 4:3 which alsoextends parallel to the barrel. Said trigger slide is normally held inits advanced position by a helical spring ll housed therein and abuttingagainst a fixed pin 45 passed through a slot- %6 in said trigger slidefor limiting the forward movement thereof, as well as for furnishing anabutment for the spring. The bottom surface of said trigger slide ischanneled out at 4:7 leaving a ratchet tooth or projection e8 facingrearwardly and extending down into the plane of said bottom surface. Thetop surface of the trigger slide is also channeled out at e9, leavingalug extending up into the plane of said top surface. The rear end ofsaid trigger slide has a bifurcation 51 cut vertically and centrallythereof and preferably extending forward to the lug 50, leaving twoseparated lateral walls at the rear end of said slide. Both of saidlateral walls 52 and 53 project above the top of the main portion of theslide. The upper edge 5% of the wall 52 is inclined upwardly andrearwardly from the main upper surface of the slide and the lower rearcorner of said wall is rounded at The upper edge 56 of the lateral wallis inclined forwardly and upwardly. Below the trigger slide there isarranged another slide 54' which I have called the hammer-actuatingslide. This slide moves parallel to the trigger slide and is nori'nallyheld in advanced position by a helical spring housed therein andabutting against a fixed pin 59 passed through a horizontal slot (30 insaid slide. he rear end of this slide has a vertical bifurcation ('31formed therein with registering perforations 62 in the sides thereof.Pivotally mounted in said bifurcation. by means of a pivot pin 63engaging said perforations 62. is what I call a two-part connectionbetween the trigger slide and the hammer. One part ti-t of saidconnection is pivoted intermediate of its ends in a fork 65 at theforward end of the other part 66. The forward end of the part- 65': isnormally held by means of a spring 67, up in the plane of the top of theslide 57,

and is provided with a ratchet tooth 68 facing forward and adapted toengage the ratchet tooth 48 on the bottom of the trigger slide. The rearend of said part G l normally extends below the rear end of the slide 57and its lower corner is rounded off, as at 69. The part 66 is connectedat its rear end to the hammer TO by a safety hinge joint comprising aT-shaped head T1 on the part (36 engaging a transverse slot 72 in thehammer, and the reduced shank 73 of said T- shaped head confined in arecess 'T-t in the lower wall of the slot 72. The opening 75 leading tothe slot 72 is of smaller diameter than said slot. This makes it neces;ry for the head 71 to be introduced endwise into said slot. the shankT3, of course. fitting the opening 75. It will thus be seen that whenthe part 66 is connected with the hammer and assumes its normalposition. there is no chance of said parts working loose or becomingseparated in the revolver.

The hammer is pivoted at its lower end upon a pin 76. Below said pivotthe hammer 15 provided with a forwardly extending The firing pin TSextends through an; opening 111 a rigid rertieal p1rt1t1on S6 arrangedt'ansversely of the part 1 of the revolver just r arward ot' thecylinder l. l A, vertically movable hammer locking block 97 is locatedbehind said partition and i:

1 The cylinder 4 is locked in each of its lpositions by a lever 105intermediatelv pivoted on. a fixed pin 10 and having a lug 107projecting upwardly from one of its ends into engagement with one of aseries iot' notthes 108 in the periphery of the cylinder. These notchesare spaced equidistant apart and eor'espond to the ear tridge chambersin the cylinder. The lug it)? is preferably rounded and adapted to riden a shallow groove 109 between the notches 108. Said lug; 1O?- normallyheld in engagement with said groove or said notches by a spring 110bearing upon the other end of the lever 103.

The head 117 of said pin engages theouter face of one of the lateral projections 116. The other end of saidpin is bored and tapped to receive a screw 118, the head of whichengages the outer surface of the other lateral projection 116 whenscrewed into the end of the pin 115 whereby said pin is retained inplace and the cap 112 is rigidly secured upon the revolver. Said cap ismade to exactly tit and conform to the other parts of the revolver sothat when it is in place, the joint between them will hardly bediscernible and dust and dirt will be excluded from said joint. Then thecap is to be removed, it is only necessary to take out the screw 118 andremove the pin 115, whereupon the hook 113 may be readily disengagedfrom the lug 11st when the revolver is opened or broken.

is hereinbefore indicated, the hinged part 2 of the revolver is securedin closed position upon the main portion 1 thereof by two locks. Theupper lock consists of a springpressed latch 119, see Figs. 13 and 1%,arranged at the rear end of the part 2 so that it projects over thepartition 86 on the part 1. Said latch is slidably mounted in a recess120 in the rigid portion of the part 2 which extends over the cylinder.The rear end of said latch is formed with lateral projections 121 whichextend slightly beyond the sides of the revolver and are milled orroughened so as to be readily engaged by the thumb and finger. Avertical passage 12-2 in the latch 119 has a rearwardly projectingratchet tooth 123 on its front wall. lVhen the revolver is closed, thatis the part 2 is closed down upon the part 1, this ratchet tooth 123snaps into engagementwith a hooked projection or lug 124; on the upperedge of the partition 86, thereby looking the two parts of the revolvertogether. lVhen it is desired to release the lock, the projections 121are gripped between the thumb and finger and moved forwardly until theratchet tooth 123 is disengaged from the hooked lug 12%.

The second or safety lock comprises pivoted member 125 mounted on themain 1 portion 1 of the revolver just in front of the cylinder and abovethe trigger slide. Said pivoted member is angular in shape, having onearm 126 extending upwardly from the i pivot 127 and the other arm 128extending forwardly therefrom. The upwardly extending arm has a ratchethook 129 formed on its forward edge and adapted to engage a similar butinverted hook 130 on the part 2 of the revolver. A spring 131 engagesthe rear edge of said arm 126 and normally presses the same forward sothat the hook 129 will engage the hook 130 when the part- 2 is closedupon the part 1. Milled lateral project-ions 132 extend from the arm 126of the locking member 125, slightly beyond the sides of the revolverwhere they may be engaged by the thumb and finger for retracting anddisengaging the hook 129 from the hook 1.30. lVhen the revolver isopened, that is when the part 2 is spread away from the part 1, thespring 131 press- .ing against the arm 126 of the locking member 125causes the other arm 12S thereof to drop down behind a shoulder on thetrigger slide, thereby automatically locking said trigger from beingpressed while the revolver is in its open position. It will thus be seenthat the locking member 125 serves the double function of a safety lockfor holding the two parts of the revolver together and also of a safetylock for preventing the rearward movement of the trigger when therevolver is open.

From the foregoing description, it will be seen that, when the revolveris closed and the firing mechanism is in its normal position, asillustrated in Fig. 2-, the trigger slide and hammer-actilating slideare held in their advanced positions by their springs, the hammer is inits advanced. position but held in safety position by the block 97 whichis supported in its raised position upon the inclined upper edge of thelateral wall 52 at the rear end of the trigger slide, the cylinder islocked by the lug on the lever 105 engaging one of the notches 10Stherein, and the revolving device is in its lowered and retractedposition with its rounded lower edge 10 1 resting upon the lower portionof the i clined upper edge 56 of the other lateral wall at the rear endof the trigger slide. It will be observed that when the parts are inthis position, the lug on the trigger slide is arranged in front of thei-shaped lug 111 on the bottom of the cylinder locking lever 195, andthat the ratchet tooth 18 on said trigger slide is arranged in front ofand engaged with the ratchet tooth G8 on the intermediately pivoted part6% of the two-part connection between the trigger slide and hammer. llhen the trigger is pressed, moving the trigger slide rearwardly, thehammer-actuating slide is moved with it by reason of the engagement ofthe ratchet teeth' lS and GS, and the hammer is retracted by reason ofthe connection 6 between it and said hainmer-actuating slide. As thetrigger slide moves rearwardly, the lug 50 engages the lug 111 on thecylinder locking lever 105 and operates to withdraw the lug 10? on saidlever from its notch in the cylinder. lVhile the cylinder is beingunlocked in this way, the revolving device 93 has been traveling up theinclined edge 56 of the lateral wall on said trigger slide, so that bythe time the lug on said lock has been entirely withdrawn from the notchin the cylinder, said revolving device has been raised to the of thehammer connection.

position indicated in dotted lines in Fig. 12 with its end in engagementwith one of the ratchet teeth 99 on the end of the cylinder. As thetrigger slide travels still farther rearward, the revolving devicetravels farther up the inclined edge 56 with the result that thecylinder is revolved until the next one of the notches 10S therein isbrought into register with the lug 107 on the locking lever 105. In themeantime, the lug 50 on the trigger slide has passed the lug 11 on thebottom of the locking lever 105 and said lever has been returned tonormal position by the spring 110 so that the log 10? on said leverengages the notch 108 which has been brought into register therewith andthus locks the cylinder in position for the firing of a cartridge.

All of the operations just described in sequence will have taken placebefore the trigger slide reaches the limit of its rearward movement.During this operation, however, the hammer has been swung back therequisite distance and the projection 77 on the lower end thereof hasbeen raised into the path of the rear end (39 of the intermediatelypivoted part (3% of the two-part connection between the trigger slideand the hammer. As the trigger slide reaches the end of its rear stroke,said lug 77 comes into contact with said rear end (39 of the part (iiand raises it thereby withdrawing and disengaging the ratchet tooth (28on said part 64 from the ratchet tooth l8 on the trigger slide. Themoment these ratchet teeth are disengaged, the spring 58 throws theslide 5? forward bringing the hammer with it and firing the cartridge.When the pressure of the finger is removed from the trigger slide, itsspring 1+. moves it forward and returns all of the parts to theirinitial positions. In doing so, the safety locking block 97 is pushed upbetween the partition 86 and the lug 79 on the hammer and the cylinderlock is merely withdrawn momentarily from its; notch in the cylinder asthe lug 50 on the trigger slide passes under the lug 11.1

the ratchet tooth 68 on the on its lock. As the trigger slide reachesthe end of its front stroke, the ratchet tooth l8 thereon snaps intoengagement again with the ratchet tooth (38 on the pivoted part (it henit preferred to operate the re volver as one of the hammer type, insteadof a automatically, the cap 112 removed and the hammer withdrawn, byengaging the thumb with the thumb-piece 80, until the, hook 81 on saidhammer interlocks with the hook 82 on the springpressed retainer 83. Theoperations resulting from the reciprocation of the trigger slide, inthis case, are the same as already described except that the hammer isreleased in a different way. The i hammer-actuating slide 57 has beenpreviously withdrawn with the hammer and below the plane of the ratchettooth 48 on the trigger slide by the engagement of the projection 7'? onthe hammer with the rear end of said part 64 in the retracted positionsof said hammer and its actuating slide. As the trigger slide reaches theend of its rear stroke, and after its ratchet tooth &S has passed theratchet tooth (38, the lower rounded corner 55 on the lateral wall 52 atthe rear end of said slide engages the beveled forward projection 84 onthe lower end of the retainer 83, thereby releasing the hammer which isthereupon immediately drawn forward for firing by the spring of itsactuating slide. 1

It is obvious that variations may be made in the details of constructionof my revolver, as herein shown and described, without departing fromthe spirit or sacrificing the advantages of my invention. 1, therefore,reserve the right to make such changes as fairly fall within the scopeof the appended claims.

in order to prevent the finger used for pulling the trigger frombecoming burned by sparks escaping from the breech of the revolver, Ihave provided a flange 13% ex tending along the edge of the upper part2below the barrel and cylinder and above the place cccn pied by thefinger when the. gun is m use.
